tribby 1dc5497309 Added startup protocol as requested by Devin Reed (PR#78) and Steve Reeves 
(PR#85, PR#86):
   For login shells (command line starts with '-'),
	If $PATH doesn't start with ':' or contain a space,
	   change all ":" to " ".
	source /etc/glogin
	source $HOME/glogin
$HOME/gshrc is sourced afterward for both login and non-login shells.

Don't the print number of hashed commands (from "rehash") until all
initialization is completed.

Only pass exported environment variables to child processes, and prevent child
processes from changing parent's environment.

A null command followed by a redirection of stdout, for example
  > /tmp/list
would cause an error message "<garbage> not found" due to incorrect
setting of command buffer pointer.

Filename completion did not work following ">&" or ">" without a trailing
space.

Entabbed all the asm files, saving more than 36,000 bytes.
